President Trump is populating the White House and federal agencies with former lobbyists, lawyers and consultants who in many cases are helping to craft new policies for the same industries in which they recently earned a paycheck... In at least two cases, the appointments may have already led to violations of the administration's own ethics rules. But evaluating if and when such violations have occurred has become almost impossible because the Trump administration is secretly issuing waivers to the rules.

One such case involves Michael Catanzaro, who serves as the top White House energy adviser. Until late last year, he was working as a lobbyist for major industry clients such as Devon Energy of Oklahoma, an oil and gas company, and Talen Energy of Pennsylvania, a coal-burning electric utility, as they fought Obama-era environmental regulations, including the landmark Clean Power Plan. Now, he is handling some of the same matters on behalf of the federal government.

... the Trump administration is more vulnerable to conflicts than the prior administration, particularly after the president eliminated an ethics provision that prohibits lobbyists from joining agencies they lobbied in the prior two years. The White House also announced on Friday that it would keep its visitors' logs secret, discontinuing the release of information on corporate executives, lobbyists and others who enter the complex, often to try to influence federal policy. The changes have drawn intense criticism from government ethics advocates across the city.

Mr. Trump's appointees are also far wealthier and have more complex financial holdings and private-sector ties than officials hired at the start of the Obama administration, according to an Office of Government Ethics analysis that the White House has made public. This creates a greater chance that they might have conflicts related to investments or former clients, which could force them to sell off assets, recuse themselves or seek a waiver.

...

Mr. Trump's own ethics executive order in late January eliminated a requirement, first adopted by President Barack Obama, that executive branch appointees not accept jobs in agencies they recently lobbied. That weakened standards applying to approximately 4,000 executive branch hires. Mr. Trump also made it easier for former lobbyists in the government to get waivers that would let them take up matters that could benefit former clients.
